Continuing to troubleshoot the YJ wiper linkage issue.
New data:
- I bought a YJ wiper motor gasket and it fit the CJ motor but has a gap where there is no gasket material. I added some weather stripping in that area. It seals good now.
- I sprayed water on the windshield. The wipers definitely move smoother but the clunk is still there.
- I disengaged the short side linkage going to the motor. That left the two wiper pivots attached to the long side linkage.
- Manually moving the wiper arms - they move freely through their entire range. Adding water on the windshield makes them very slick.
- I loosened the wiper motor mounting bolts and ran the motor. The video below shows it in operation that way.
- With the motor bolts loose, you can see the motor moves side to side with the linkage direction.
- New video
I believe this tells me the motor arm or short linkage is too short and at the horizontal ends of the motor cycle, it needs more length.
Do you agree?
I spoke with Matt at Riptech and he has a slightly longer YJ motor arm. Not sure it is long enough for me though. He is a great guy and is helping me even though I have not purchased anything from him. He's going to let me know after looking at the new video.
Remember, I have the CJ motor swapped with a YJ motor arm. (that has the YJ ball mount setup)
One option that is to cut the ends off the YJ short linkage and put a threaded rod between the ends and adjust it to work properly. I think someone on the forum here did this with their CJ linkage.
